MOMENI, M. M.. Evaluation of the Performance of Pt-MWCNTs Nanocomposites Electrodeposited on Titanium for Methanol Electro-oxidation. Port. Electrochim. Acta [online]. 2015, vol.33, n.6, pp.331-341. ISSN 0872-1904.  https://doi.org/10.4152/pea.201506331.

Pt nanoparticle-multi walled carbon nanotubes nanocomposites supported on titanium substrate (Pt-MWCNTs/Ti) were prepared by co-electrodeposition method. This composite catalyst was characterized by scanning electron microscopy (SEM), energy dispersive spectrum (EDS), and electrochemical methods. The SEM images reveal that nanostructures are distributed at the surface of the titanium plate. Electro-oxidation of methanol was investigated in acidic media on Pt-MWCNTs/Ti electrodes via cyclic voltammetric analysis in the mixed 0.1 M methanol and 0.1 M H2SO4 solutions. The Pt-MWCNTs/Ti catalyst has good electro-catalytic activity for methanol oxidation. This novel Pt-MWCNTs/Ti catalyst can be used repeatedly and exhibits stable electrocatalytic activity for the methanol oxidation.
